Shelly Plus Smoke Alarm is a smart wireless smoke alarm that detects smoke and sends a notification directly to your smartphone, even when you are away from home. The sensitive optical smoke sensor effectively detects smoke produced by slow, smouldering fires, while the powerful alarm sound of at least 85 dB and flashing LED indicator provide a clear warning in the event of danger. The battery-powered device is easy to install without electrical wiring, and its designed service life is up to 10 years. Thanks to its compact and discreet design, the smoke alarm blends neatly into your home interior.
Shelly Plus Smoke Alarm connects directly to your home Wi-Fi network, allowing it to be integrated into your home automation system without a separate hub. When smoke is detected, the smoke alarm activates both an audible and visual alarm and sends a notification to your smartphone via the Shelly Smart Control app, allowing you to react quickly to a potential emergency. The smoke alarm can also be connected with other Shelly devices to create automations that, for example, switch on the lights or cut power to electrical devices when an alarm is triggered. Local control of compatible devices is also possible without an internet connection.
Easy to install, Shelly Plus Smoke Alarm is suitable for homes, holiday homes and other residential spaces. The smoke alarm is powered by one replaceable CR123A battery, so no separate power supply or fixed electrical installation is required. The device features a convenient test button for checking its operation, as well as a temporary mute function for silencing unwanted alarms. When the battery level becomes low, the device indicates that the battery needs to be replaced with an audible warning. Shelly Plus Smoke Alarm complies with the requirements set for smoke alarms (EN 14604 standard). Three-year (36-month) warranty!
